Abstract
A pump control system for controlling a fluid pump powered by an AC signal. The pump control system includes a signal phase detector coupled to the fluid pump to detect the AC signal supplied to the fluid pump and to generate phase signals indicating a phase parameter of the AC signal. The pump control system also includes a micro-controller to receive the phase signals and to generate a rectified output signal based on the phase signals, and a relay to control the power supplied to the fluid pump based on the output signal of the micro-controller.
